Nothing compares to iOS's lost mode, it ties deep into the device's hardware.
No Android device has a feature that's similar to iOS 7's activation lock. Even Samsung's Note 3 "equivalent" could surely be done away with by flashing CM.

Android (MUST) add feature!
How the best Mobile OS could lack this feature?

By not being manufactured by the same company as mentioned by another member, Apple's Lost Mode ties deep into hardware which requires certain hardware support, which is not the case for Android phones since the software and hardware are by different companies.

Avast mobile security has functions and features like this with things in place to prevent flashing recoveries and such like, but to be fair, once your phone is stolen the only need of security software is to ensure your data is wiped. Everything else is unimportant as people will always find a way to reactivate a phone eventually, and you are very unlikely to get it back.

All of the manufacturers use the same API and OS, Android must release such an API then the manufacturers can compile them into there Firmware...

Not really. API levels differ between Android versions, so different Android versions can have different sets of API available. Google could arguably incorporate such a feature into Google Play Services, but then the hardware portion is missing so even if manufacturers had such an option, the prerequisite hardware support must be present and unfortunately pretty much all Android devices to my knowledge don't have such a thing
